[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially identical. Note that in this specification, ordinal numbers are used only to distinguish between parts, members, portions, positions, directions, etc., and do not indicate order or priority.
[0010] [Embodiment] FIG. 1 is a perspective view of a wire harness WH according to an embodiment. The wire harness WH of this embodiment shown in FIG. 1 is installed in a vehicle such as an automobile. Here, the wire harness WH is, for example, a collective component in which a plurality of shielded electric wires 10 serving as electric wires used for power supply and signal communication are bundled together to connect various devices mounted on the vehicle, and the shielded electric wires 10 are connected to the devices using connectors or the like. The wire harness WH of this embodiment includes, for example, a plurality of conductive shielded electric wires 10 and a shield shell 1 provided at the ends of the plurality of shielded electric wires 10 and grounded to the shielded electric wires 10. In this embodiment, the shield shell 1 is an example of a grounded object. The wire harness WH may further include a protector, a grommet, or the like.
[0011] In the following description, of the first, second, and third directions that intersect with one another, the first direction will be referred to as the "axial direction X," the second direction will be referred to as the "width direction Y," and the third direction will be referred to as the "height direction Z." Here, the axial direction X, the width direction Y, and the height direction Z are approximately perpendicular to one another. The axial direction X typically corresponds to the extending direction (axial direction) of the shielded electric wire 10, the insertion direction of the shielded electric wire 10 into the shielded shell 1, the longitudinal direction of the shielded shell 1, etc. The width direction Y typically corresponds to the radial direction of the shielded electric wire 10, the width direction (left-right direction) of the shielded shell 1, etc. The height direction Z typically corresponds to the radial direction of the shielded electric wire 10, the height direction (up-down direction) of the shielded shell 1, the stacking direction of the laminates 2 and 3 described below, etc. Furthermore, unless otherwise specified, the directions used in the following description will be described as directions in a state in which the shielded electric wire 10 is assembled to the shielded shell 1.
[0012] FIG. 2 is an exploded perspective view of the wire harness WH. As shown in FIG. 2, the wire harness WH includes, for example, a plurality of laminates 2 and 3 stacked along the height direction Z, and a plurality of fastening members 4, such as bolts, that fasten the plurality of laminates 2 and 3 together. In this embodiment, the laminates 2 and 3 are formed of unit components (modules) that are substantially identical to each other. That is, the specifications of the laminate 2 are substantially the same as the specifications of the laminate 3. Here, the laminate 2 is provided with boss-hole-shaped mounting portions 1b into which the fastening members 4 are fastened, while the laminate 3 is provided with mounting hole-shaped mounting portions 1b into which the fastening members 4 are inserted, and the other configurations are substantially the same. The mounting portions 1b are provided, for example, at the four corners of the laminates 2 and 3.
[0013] The laminates 2 and 3 are each configured to include, for example, a plurality of shielded electric wires 10 and a shield shell 1 that houses the plurality of shielded electric wires 10. The shield shell 1 grounds the plurality of shielded electric wires 10 and, by covering the periphery of the shielded electric wires 10, prevents noise and the like from leaking outside the shield shell 1. The shield shell 1 is configured, for example, by combining a plurality of parts. Here, as an example, the shield shell 1 is configured to include an upper shell 1A and a lower shell 1B. The upper shell 1A and the lower shell 1B are each formed, for example, from a conductive metal material.
[0014] 3 is an exploded perspective view of the laminate 2. As shown in FIG. 3, the lower shell 1B is a portion of the shield shell 1 that covers the multiple shielded electric wires 10 from the other end side (lower side) in the height direction Z. The lower shell 1B is provided with a concave accommodation space 1e that is open toward one end side (upper side) in the height direction Z and accommodates the multiple shielded electric wires 10. In the accommodation space 1e, the multiple shielded electric wires 10 are arranged side by side at intervals from each other in the width direction Y. The lower shell 1B also has multiple fastening holes 1d to which fastening members 5 such as bolts are fastened along the height direction Z. The multiple fastening holes 1d are provided, for example, at four corners of the lower shell 1B in proximity to the mounting portion 1b, and are fastened (integrated) with the upper shell 1A via the fastening members 5 fastened to the fastening holes 1d.
[0015] The upper shell 1A is a portion of the shield shell 1 that covers the multiple shielded electric wires 10 from one end side (upper side) in the height direction Z. With the multiple shielded electric wires 10 accommodated in the accommodation space 1e of the lower shell 1B, the upper shell 1A covers the accommodation space 1e from one end side (upper side) in the height direction Z. The upper shell 1A, together with the lower shell 1B, constitutes the main body 1a of the shield shell 1. The upper shell 1A is provided with multiple insertion holes 1c through which the above-mentioned fastening members 5 are inserted along the height direction Z. The multiple insertion holes 1c are provided, for example, at positions corresponding to the multiple fastening holes 1d of the lower shell 1B. The fastening members 5 are inserted into the respective insertion holes 1c and fastened to the fastening holes 1d, thereby fastening (integrating) the upper shell 1A and the lower shell 1B together.
[0016] In this embodiment, each of the multiple shielded electric wires 10 is exteriorly covered with a shield terminal 20, a shield ring 30 (see FIG. 4), a packing 40, and a shrinkable tube 50. The shield terminal 20 is a terminal fitting made of a conductive metal material, and is grounded to the shield shell 1. The shield terminal 20 is configured to include, for example, a cylindrical portion 21 (see FIG. 4) that covers the outer circumferential surface of the shielded electric wire 10 and is housed inside the shrinkable tube 50, and an exposed portion 22 that is provided at one end of the cylindrical portion 21 in the axial direction X and is exposed to the outside of the shrinkable tube 50.
[0017] In this embodiment, the exposed portion 22 protrudes in a crank shape from one end side of the shrinkable tube 50 in the axial direction X along the side surface 41a and outer peripheral surface of the packing 40 (packing body 41). The tip end of the exposed portion 22 extends along the inner surface of the upper shell 1A and the inner surface of the lower shell 1B described above, and is grounded to the inner surface of the upper shell 1A and the inner surface of the lower shell 1B. The shield terminal 20 is formed, for example, by forming a single piece of sheet metal by various processes such as pressing and bending into shapes corresponding to the respective parts of the tubular portion 21 and the exposed portion 22, so that each part is three-dimensionally and integrally formed.
[0018] Fig. 4 is a cross-sectional view of the laminate 2. As shown in Fig. 4, the shielded wire 10 includes, for example, a linear conductor portion 11 having electrical conductivity, an insulating coating portion 12 having electrical insulation and covering the outside of the conductor portion 11, and a braided body 13 disposed between an inner layer 12a and an outer layer 12b of the insulating coating portion 12. Note that the conductor portion 11 in this embodiment is a core wire formed by bundling a plurality of conductive metal element wires, but it may also be a twisted core wire formed by twisting the plurality of metal element wires together. The insulating coating portion 12 is a wire coating that covers the outer periphery of the conductor portion 11.
[0019] The shielded electric wire 10 extends linearly along the axial direction X and is formed to extend with approximately the same diameter in the axial direction X (extension direction). In addition, the shielded electric wire 10 is formed such that, for example, the cross-sectional shape (cross-sectional shape intersecting with the axial direction X) of the conductor portion 11 is approximately circular, and the cross-sectional shapes of the insulating coating portion 12 and the braided body 13 are approximately annular, so that the shielded electric wire 10 has an approximately circular cross-sectional shape as a whole. In this embodiment, for example, the inner layer 12a of the insulating coating portion 12 and the conductor portion 11 form a wire main body of the shielded electric wire 10, and the outer layer 12b of the insulating coating portion 12 and the braided body 13 form a shield portion of the shielded electric wire 10.
[0020] The shielded wire 10 is configured to include, for example, a first portion 10a and a second portion 10b. The first portion 10a is a portion of the shielded wire 10 that is located closer to one end in the axial direction X than the shield ring 30. The first portion 10a is configured to include the conductor portion 11 and the inner layer 12a of the insulating coating portion 12 that constitute the above-mentioned wire main body, and the braided body 13 and the outer layer 12b of the insulating coating portion 12 that constitute the shield portion, and is formed to have a relatively larger diameter than the second portion 10b.
[0021] The second portion 10b is a portion of the shielded wire 10 that is located closer to the other end in the axial direction X than the shield ring 30. The second portion 10b is configured to include only the conductor portion 11 and the inner layer 12a of the insulating coating portion 12 that constitute the above-mentioned wire main body, and is formed to have a smaller diameter than the first portion 10a. That is, the shielded wire 10 includes a portion in the axial direction X where the braided body 13 and the outer layer 12b of the insulating coating portion 12 that constitute the above-mentioned shield portion have been stripped away, and this portion constitutes the second portion 10b.
[0022] The braid 13 is a shielding layer formed by weaving a conductive metal material into a mesh. The braid 13 includes, for example, a main body 13a that covers the outer peripheral surface of the inner layer 12a of the insulating coating 12 that constitutes the above-described electric wire main body, and a folded-back portion 13b that is provided at the other end of the main body 13a in the axial direction X and folded back along the outer peripheral surface of the shield terminal 20. The main body 13a is formed, for example, in a cylindrical shape extending along the axial direction X, and is interposed between the inner layer 12a and the outer layer 12b of the insulating coating 12. In this embodiment, the main body 13a covers the conductor 11 and the inner layer 12a of the insulating coating 12 of the shielded electric wire 10 over substantially the entire length of the shielded electric wire 10, thereby configuring the electric wire as the shielded electric wire 10.
[0023] The folded portion 13b is formed, for example, in a cylindrical shape extending along the axial direction X, and is interposed between the shield terminal 20 and the shield ring 30. The folded portion 13b is formed by folding back the other end of the main body portion 13a in the axial direction X so that it overlaps the outer peripheral surface of the shield terminal 20. The length of the folded portion 13b in the axial direction X is approximately the same as the length of the shield ring 30 in the axial direction X. The main body portion 13a is also referred to as an inner shield portion, etc., and the folded portion 13b is also referred to as an outer shield portion, etc.
[0024] The shield ring 30 functions as a crimping ring that is crimped to the braid 13. The shield ring 30 is formed, for example, in a cylindrical shape that follows the outer peripheral surface of the shield terminal 20, and is crimped and fixed so that the folded-back portion 13b of the braid 13 is sandwiched between the shield ring 30 and the shield terminal 20. In this embodiment, the shield ring 30, the folded-back portion 13b of the braid 13, and the shield terminal 20 are crimped and fixed together, thereby forming a stepped portion (recess) in the radial direction (height direction Z) in the shield terminal 20. The shield ring 30, the folded-back portion 13b of the braid 13, and the shield terminal 20 are crimped and fixed together, thereby electrically connecting the shield ring 30, the braid 13, and the shield terminal 20. The shield ring 30 is also referred to as a sleeve, etc.
[0025] The packing 40 prevents foreign matter such as moisture from entering the crimped and fixed portion formed by the shield ring 30. The packing 40 is made of an elastically deformable material such as rubber or resin. The packing 40 is formed, for example, in a cylindrical shape along the outer circumferential surface of the first portion 10a of the shielded electric wire 10 and is fitted onto the outer circumferential surface of the first portion 10a. That is, the packing 40 prevents water from entering between the outer circumferential surface of the first portion 10a of the shielded electric wire 10, which is located closer to one end of the shield ring 30 in the axial direction X, and the packing 40 prevents water from entering from the outer circumferential surface of the first portion 10a toward the shield ring 30.
[0026] The packing 40 includes, for example, a packing body 41, an inner lip portion 42, and an outer lip portion 43. The inner lip portion 42 protrudes radially inward from the inner circumferential surface of the cylindrical packing body 41 and seals the gap with the outer circumferential surface of the first portion 10a. In this embodiment, two inner lip portions 42 are provided on the inner circumferential surface of the packing body 41, aligned in the axial direction X. The inner lip portions 42 are pleated water-stopping portions formed in a substantially annular shape along the inner circumferential surface of the packing body 41. When the first portion 10a is inserted (press-fitted) into the packing body 41, the inner lip portions 42 contact the outer circumferential surface of the first portion 10a to seal the gap with the outer circumferential surface. The inner lip portions 42 are configured to elastically deform to closely contact the outer circumferential surface of the first portion 10a and seal the annular space between the outer circumferential surface and the inner circumferential surface of the packing body 41.
[0027] The outer peripheral lip portion 43 protrudes radially outward from the outer peripheral surface of the packing body 41 and presses the exposed portion 22 of the shield terminal 20 against the shield shell 1. In this embodiment, two outer peripheral lip portions 43 are provided on the outer peripheral surface of the packing body 41, aligned in the axial direction X. The two outer peripheral lip portions 43 are aligned with the two inner peripheral lip portions 42 in the radial direction (height direction Z). The outer peripheral lip portion 43 is a pleated water-stopping portion formed in a substantially annular shape along the outer peripheral surface of the packing body 41. When the packing body 41 is housed in the shield shell 1, the outer peripheral lip portion 43 contacts the inner peripheral surface of the exposed portion 22 to seal the space between the inner peripheral surface and the outer peripheral surface of the packing body 41. The outer peripheral lip portion 43 is configured to elastically deform and closely contact the inner peripheral surface of the exposed portion 22, sealing the annular space between the inner peripheral surface and the outer peripheral surface of the packing body 41. Moreover, the outer peripheral lip portion 43 is brought into close contact with the inner peripheral surface of the exposed portion 22 due to elastic deformation, and presses the exposed portion 22 toward the shield shell 1.
[0028] The shrink tube 50 is, for example, a heat-shrinkable tube that shrinks in the radial direction (height direction Z) when heated, and prevents foreign matter such as moisture from entering the crimped and fixed portion formed by the shield ring 30. The shrink tube 50 is, for example, formed in a cylindrical shape that follows the outer circumferential surface of the second portion 10b of the shielded electric wire 10, and is tightly fixed to the outer circumferential surface of the second portion 10b by heat shrinkage. In this embodiment, the shrink tube 50 integrally covers the outer circumferential surfaces of the second portion 10b, the shield ring 30, and the shield terminal 20, and prevents water from entering the shield ring 30 from the outer circumferential surface of the second portion 10b of the shielded electric wire 10, which is located closer to the other end of the shield ring 30 in the axial direction X.
[0029] Moreover, the shrink tube 50 is configured to include, for example, a first seal portion 51, a second seal portion 52, and a connection portion 53. The first seal portion 51 is a portion of the shrink tube 50 that integrally covers the outer peripheral surface of the shield ring 30 and the outer peripheral surface of the shield terminal 20, and seals the gap between the outer peripheral surface of the shield ring 30 and the outer peripheral surface of the shield terminal 20. The first seal portion 51 is formed in a cylindrical shape that follows the outer peripheral surfaces of the shield ring 30 and the shield terminal 20, and is formed with a diameter that is relatively larger than that of the second seal portion 52.
[0030] The second seal portion 52 is a portion of the shrink tube 50 that covers the outer peripheral surface of the second portion 10b of the shielded electric wire 10 and seals the gap with the outer peripheral surface of the second portion 10b. The second seal portion 52 is formed in a cylindrical shape that follows the outer peripheral surface of the second portion 10b and has a smaller diameter than the first seal portion 51. The connection portion 53 is a portion of the shrink tube 50 that is provided between the first seal portion 51 and the second seal portion 52 and connects the first seal portion 51 and the second seal portion 52. The connection portion 53 is formed, for example, in a stepped shape recessed along the radial direction (height direction Z) of the shrink tube 50.
[0031] The shrink tube 50 includes, for example, a cylindrical base layer and an adhesive layer 60 provided on the inner circumferential surface of the base layer. The base layer is formed of, for example, a resin material that shrinks when heated, such as polyolefin or a fluoropolymer. The adhesive layer 60 is formed of, for example, a hot-melt adhesive, more specifically, a polyolefin such as polyethylene, a thermoplastic polyester, an ethylene-vinyl acetate copolymer, or a polyamide. In this embodiment, the adhesive layer 60 is provided over substantially the entire inner circumferential surface of the shrink tube 50. That is, the adhesive layer 60 is provided on each of the inner circumferential surfaces of the first seal portion 51, the second seal portion 52, and the connection portion 53.
[0032] Before being thermally shrunk by heating, the shrinkable tube 50 is formed into a cylindrical shape with a diameter larger than the outer circumferential surface of the shielded terminal 20. Then, by thermally shrinking the shrinkable tube 50 so as to be in close contact with the outer circumferential surface of the second portion 10b of the shielded wire 10, the outer circumferential surface of the shield ring 30, and the outer circumferential surface of the shielded terminal 20, the first seal portion 51, the second seal portion 52, and the connection portion 53 can be formed. In this way, in this embodiment, by using the shrinkable tube 50, it is possible to relatively easily prevent water from entering the crimped and fixed portion side of the shield ring 30.
[0033] Here, if a pair of packings 40 were provided on both sides of the crimped and fixed portion by the shield ring 30 in the axial direction X, packings 40 with various specifications according to the wire diameter of the shielded electric wire 10 would be required, which could increase the effort and cost required for manufacturing the wire harness WH. In this regard, according to the present embodiment, the number of packings 40 can be reduced by using the shrink tube 50. This has the advantage of reducing the effort and cost required for manufacturing the wire harness WH and making the wire harness WH more compact in the radial direction of the shielded electric wire 10.
[0034] As described above, the wire harness WH of the present embodiment includes the packing 40 having the packing body 41 that covers the outer peripheral surface of the first portion 10 a of the shielded electric wire 10, which is located closer to one end of the shielded electric wire 10 in the axial direction X than the shield ring 30, and the inner lip portion 42 that protrudes radially inward from the inner peripheral surface of the packing body 41 and forms a seal with the outer peripheral surface of the first portion 10 a, and the shrink tube 50 that integrally covers the outer peripheral surface of the second portion 10 b of the shielded electric wire 10, which is located closer to the other end of the shielded electric wire 10 in the axial direction X than the shield ring 30, the outer peripheral surface of the shield ring 30, and the outer peripheral surface of the shield terminal 20, and forms a seal with the outer peripheral surface of the second portion 10 b. With this configuration, the wire harness WH can, for example, prevent water from entering the shield ring 30 side from the outer peripheral surface of the first portion 10a of the shielded electric wire 10, which is located closer to one end in the axial direction X than the shield ring 30, by the packing 40, and can also prevent water from entering the shield ring 30 side from the outer peripheral surface of the second portion 10b of the shielded electric wire 10, which is located closer to the other end in the axial direction X than the shield ring 30, by the shrinkable tube 50. As a result, the wire harness WH can appropriately prevent water from entering the crimped and fixed portion formed by the shield ring 30.
[0035] In the wire harness WH of this embodiment, the shield terminal 20 has an exposed portion 22 that protrudes in a crank shape from one end side of the shrinkable tube 50 in the axial direction X along the side surface 41a and outer peripheral surface of the packing body 41 and is grounded to the shield shell 1 (grounding target). With this configuration, the wire harness WH can, for example, relatively easily ground the shield terminal 20 to the shield shell 1 located on the outside by the exposed portion 22.
[0036] Furthermore, in the wire harness WH of this embodiment, the packing 40 has an outer peripheral lip portion 43 that protrudes radially outward from the outer peripheral surface of the packing body 41 and presses the exposed portion 22 toward the shield shell 1. With this configuration, the wire harness WH can more reliably maintain the grounded state between the exposed portion 22 and the shield shell 1 by, for example, the elastic force of the outer peripheral lip portion 43, and can also suppress water from entering through the gap between the packing 40 and the shield terminal 20 toward the shield ring 30.
[0037] In this embodiment, the wire harness WH is exemplified as including two laminates 2, 3 stacked along the height direction Z, but the number of laminates 2, 3 is not limited to this example, and for example, the wire harness WH may be configured to include one, three or more laminates 2, 3.
[0038] While the embodiments of the present invention have been described above, they are merely examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other forms, and various omissions, substitutions, combinations, and modifications can be made without departing from the spirit of the invention. Furthermore, the specifications of each configuration, shape, and the like (structure, type, direction, format, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be modified as appropriate.
